benfrog writes: "Blackberry maker Research in Motion may need to write off more than $1 billion in inventory, according to Bloomberg. The potential "writedown" comes after RIM took a $485 million pretax charge to write down the value of its PlayBook inventory in December. RIM has said it aims to save $1 billion in operating costs this fiscal year by cutting its number of manufacturing sites and is “reviewing its organizational efficiency” across the company, which may lead to job cuts of 2,000-3,000. Its shares have tumbled 75 percent over the past year and are down 90 percent from their all-time high."Link to Original Source
